True and false aneurysms of veins are very rare conditions and only few cases have been described in literature. We present a case of 56-year-old female with personal history of primary arterial hypertension and connective tissue disease. Ultrasound of the neck showed saccular, compressible, hypoechoic structure that appeared to have a direct communication with left external jugular vein lumen. The venous aneurysm was removed and the histopathology of the mass showed a grossly dilated vein, with continuous aspects of the entire three layer of the venous wall, classifying it as a venous aneurysm...

OBJECTIVES: We endeavored to prove that angiotensinⅡ (Ang Ⅱ) regulates both the expression of miR143/145 and differentiation of vascular smooth muscle cells (VSMCs) during the formation of aortic dissection. We also studied the contribution the p38 MAPK signaling pathway has towards this process. METHODS: Ascending aortic tissues were harvested from the patients with aortic dissection (AD) and organ donors.Tissues were immunostained with labeled antibodies targeting p38 MAPK,phospho-p38 MAPK,alpha-smooth muscle actin (α-SMA), and osteopontin (OPN)...

Neurofibromatosis type I (NFI), also called Von Recklinghausen disease, is an autosomal dominant disease secondary to a genetic mutation on the long arm of chromosome 17. This disorder affects neural crest cells. Cutaneous clinical forms are the most frequent with multiple benign skin neurofibromas, associated with café au lait skin spots and iris hamartomas. Vascular abnormalities in NF1 are rare but have also been well described. The most frequent abnormalities are characterized by arterial aneurysm degeneration, stenosis, and malformations...

Although small (<5cm) Abdominal Aortic Aneurysm (AAA) have been associated with symptoms and indication for intervention scarcely, the clinicians should never exclude such potential association especially in the absence of other overt pathological findings. In such cases, a surgical exploration with consequent intervention, if feasible, should be justified in order to prevent a detrimental evolution in a dubious scenario. In this article we present two cases of patients with small AAA presenting with severe abdominal pain...

We report a successful treatment of thoracic arch aneurysm using a combination of hybrid approach and a customized stent graft in a frail patient with challenging anatomy and concomitant large retrosternal goiter. The patient is an 82-year-old lady with multiple comorbidities who presented to her general practitioner for anorexia and significant weight loss. She was incidentally found to have a 6.6 cm saccular distal aortic arch aneurysm, a 5.5 cm infrarenal abdominal aortic aneurysm, and a large goiter adjacent to the left common carotid artery with retrosternal extension...

INTRODUCTION: Clinical management of wounds can benefit from objective measures of response to treatment. Wound surface area and volume are objective measures of wound healing. Using a synthetic wound model we compare the accuracy and reproducibility of two commercially available three-dimensional (3D) cameras against planimetry and water displacement. METHODS: Twelve ulcers of various sizes and colours were reproduced in modelling clay and cured. 5 naive observers used digital planimetry, water displacement, Eykona camera (Fuel 3D, UK), and Silhouette camera (ARANZ, New Zealand) to measure the wounds...

BACKGROUND: Thrombogenicity and neointimal hyperplasia are major causes for synthetic vascular graft failure. Bioactive coatings like heparin have improved patency by reducing thrombogenicity, but neointimal hyperplasia still remains an unsolved problem. Surface coatings with heparan sulfate (HS), the major component of the glycocalix of endothelial cells, have shown reduced platelet and cell adhesion in vitro. The aim of the study was to evaluate the in vivo surface properties of expanded ePTFE vascular grafts with a semisynthetic HS-like coating (SSHS)...

BACKGROUND: Endothelial progenitor cell (EPC) has significant age-dependent alterations in properties, but the role of Jagged1 in ageing-induced decline of EPC functions remains unclear. METHODS: 2 and 20 months old healthy male Sprague-Dawley rats were used in present study. Jagged1 gene transfection was performed in EPC isolated from aged (AEPC) and young rats (YEPC) respectively. Experiments were divided into four groups: a) pIRES2-EGFP (PE) group, b) PE combined N-[N-(3, 5-difluoro-phenacetyl)-1- alany1]-S-phenyglycine t-butyl ester (DAPT) (PE + D) group, c) pIRES2 EGFP- Jagged1 (PEJ) group and d) PEJ combined DAPT (PEJ+D) group...

OBJECTIVES: To evaluate the expression of immuno-histochemical markers of tissue ischemia (iNOS, eNOS and HSP70) in a vascular damage control experimental model in order to determine if a venous temporary vascular shunt insertion leads to a better limb perfusion when compared to the ligature of the injured vein. METHODS: Experimental study in male Sus Scrofa weighting 40 Kg. Animals were distributed into 5 groups: group 1 animals were submitted to right external iliac artery (EIA) shunting and right external iliac vein (EIV) ligation; group 2 animals were submitted to right EIA shunting and right EIV shunting; group 3 animals were submitted to right EIV ligation; group 4 animals were submitted to right EIV shunting; group 5 animals were not submitted to vascular shunting nor venous ligation...

Inferior vena cava (IVC) thrombosis is a rare complication of abdominal aortic aneurysm (AAA). A 70-year-old male patient of Italian origin presented with a 9.3 x 8.4 cm infrarenal AAA, which was treated by endovascular aortic repair (EVAR). He reported a history of ulcerative colitis and was on prednisolone 80 mg daily. Seven weeks postoperatively the patient was readmitted with a deep vein thrombosis including both iliac veins and IVC, and bilateral pulmonary embolism. Venous thrombectomy and decompression of the IVC was performed by partial resection of the aneurysm sac...

BACKGROUND: Complement is an important mediator in arterial blood pressure-induced vein graft failure. Previously we noted activation of cell protective mechanisms in human saphenous veins too. Here we have analyzed whether C4b-binding protein (C4bp), an endogenous complement inhibitor, is present in the vein wall. MATERIALS AND METHODS: Human saphenous vein segments obtained from patients undergoing coronary artery bypass grafting (n=55) were perfused in vitro at arterial blood pressure with either autologous blood for 1, 2, 4 or 6 hours or with autologous blood supplemented with reactive oxygen species scavenger N-acetylcysteine...

BACKGROUND: The poor clinical results that are frequently reported for arteriovenous fistulae (AVF) for hemodialysis are typically due to failure of AVF maturation. We hypothesized that early AVF maturation is associated with generation of reactive oxygen species and activation of the HIF-1 pathway, potentially promoting neointimal hyperplasia. We tested this hypothesis using a previously reported mouse AVF model that recapitulates human AVF maturation. METHODS: Aortocaval fistulae were created in C57Bl/6 mice, and compared to sham-operated mice...

BACKGROUND: With approval of on-label fenestrated (F-) endovascular aortic repair (EVAR), concerns regarding long-term patency and endoleaks (ELs) after chimney graft (CG)-EVAR were raised. To add supportive data on the value of this technique, we chose to report the mid-term results of CG-EVAR in a single center with standardized methods and to compare them to F-EVAR. METHODS: A retrospective analysis of prospectively gathered data from January 2010 to January 2015 was conducted and patients with excessive comorbidities for open repair treated by CG-EVAR or F-EVAR were included...

Epithelioid hemangioendothelioma is a rare vascular sarcoma that arises from the lining (intima) of blood vessels. We report a case of epithelioid hemangioendothelioma in a 43-year-old male patient, who presented with inferior vena cava obstruction and acute bilateral lower extremity deep vein thrombosis. Mechanical thrombectomy was performed with an endovascular thrombectomy device, followed by stent placement in the inferior vena cava. The initial pathology on the retrieved specimen revealed an undifferentiated neoplasm, and surgical resection of the retroperitoneal soft tissue tumor of the inferior vena cava documented a rare case of epithelioid hemangioendothelioma...

BACKGROUND: Transaxillary approach to first rib resection and scalenectomy (TAFRRS) is a well-established technique for treatment of thoracic outlet syndrome (TOS). Although anatomic features encountered during TAFRRS are in general constant, vascular anomalies may be encountered but have not been described to date. Herein we describe vascular abnormalities encountered during TAFRRS. METHODS: We performed a retrospective review of a prospective practice database of 224 operations for TOS performed in 172 patients from March 2000 to March 2014...
